Embed m2e lifecycle mapping metadata as META-INF/m2e/lifecycle-mapping-metadata.xml

[patrodyne]

The widely used M2Eclipse plugin for the Eclipse IDE can be instructed to execute the markdown-page-generator-plugin during the Eclipse build cycle. This will eliminate Eclipse error messages and improve the integrated build cycle. To instruct M2Eclipse, the markdown-page-generator-plugin is configured by embedding this file under src/main/resources.
